In Borderlands 2, if you have reached sanctuary and went to Moxxxi's bar, you should tip her 10k. If you do, you get an achievement (if you have never tipped her 10k before) and she pulls a gun out of her cleavage. If you get Moxxxi's Good Touch. Equip it and cycle to it. Your controller will vibrate. Comment if you get it. LOL! ^-^
